Error: found unexpected type for label '<label>' (should be array of config options)

[coilysiren]

Description:

I suspect that I'm just getting the labeler syntax wrong, but unfortunately I can't get it to work. Some assistance would be appreciated.

I'm getting the same error message as https://github.com/actions/labeler/issues/716

Action v5:

Platform:

• [x] Ubuntu
• [ ] macOS

Expected behavior:

Labels are added. Or at least, CI doesn't fail.

Actual behavior:

Error: found unexpected type for label 'javascript' (should be array of config options)

It looks like this might be the issue?

Unfortunately I was expecting the labeler run inside of a PR branch to actually use the configuration from that PR branch! Probably a naive assumption on my part.

After merging I'm getting a new error:

Error: Error: found unexpected type for label '0' (should be array of config options)
